Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

Learners will compare the growth rate and appearance of crystals forming on small rocks to those growing on miscellaneous objects. Learners will also investigate how temperature (warm vs.

This simple construction activity teaches the importance of architectural structure. Learners build and test designs for a paper "doghouse" strong enough to hold the weight of a jumbo dog biscuit.

In this math lesson, learners identify, describe, and construct the five regular polyhedra.

The goal of this activity is to design, build and test a house or toy for an animal.

In this activity, learners build a paper stellated rhombic dodecahedron, a three-dimensional 12-pointed star.

In this activity, learners repeat patterns in two and three dimensions to create tessellations.

In this activity, learners discover how to rotate a flat shape into the third dimension. Learners draw and cut out a shape that has at least one straight edge on an index card.

In this activity, learners explore the structural strength of triangles by creating their own free-standing geodesic dome out of plastic straws.

In this activity, learners create 3D geometric shapes using straws and pipe cleaners.

In this activity, learners develop spatial reasoning skills as they blow bubbles and observe what happens when the bubbles connect.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.

Build a house you can fit inside, using cardboard tubes.

In this activity, learners repeat patterns in two and three dimensions to create tessellations. This activity combines the creativity of an art project with the challenge of solving a puzzle.

In this activity, learners will participate in a scavenger hunt involving sizes, shapes, and numbers. This activity works well with a whole group, individuals, or families.

In this activity, learners practice drawing 3D structures in two dimensions. Learners draw cube stacks from five different points of view.

In this activity, learners explore the relative sizes and distances of objects in the solar system.
